A system for detecting slope collapse
SLOPE COLLAPSE DETECTION SYSTEM
KS Certification : R-RMM-bon-BON-100S
KS Certification : R-RMM-bon-BON-200G
It is a system for preventing disasters so that casualties can be avoided as much as possible through detecting risks of collapse that occur in places close to residential areas, such as cutting areas on roads and retaining walls and embankments in downtown residential districts, during the thawing season or the rainy season, in particular.
Main components include wireless sensors and nodes for measuring slopes, remote wireless gateways (RRG: Remote Radio Gateway: equipped with modems for controlling and communication), and solar batteries. This is a system for controlling and managing through server systems of related organizations.
